Daily Latte Factor Calculator

Total Contributed is a simple running sum of the monthly amount with no growth applied, while Future Value If Invested compounds every contribution at the assumed monthly rate for however long remains in the horizon -- money contributed in year one has decades to compound by the end of a 30-year horizon, so the earlier contributions do most of the work in widening the gap between the two totals.

No -- Weekly, Monthly, and Annual Total are pure multiples of the daily expense and do not reference the investment return rate at all; changing the assumed return only changes what that same spending could have become if invested, shown separately as Future Value If Invested, not the recorded cost of the habit itself.

Both totals increase as the horizon lengthens, but Future Value If Invested grows faster than a straight line because more years means more compounding periods on top of the additional contributions, while Total Contributed only grows in direct proportion to the extra months -- the longer the horizon, the larger the share of the final balance that comes from growth rather than from money actually set aside.

Not necessarily -- this calculator applies whatever annual return rate is entered as a constant across the entire time horizon, so a higher input always produces a larger projected future value, but it does not check that rate against historical market returns or account for the year-to-year volatility a real investment would experience.
